General Physics Wed, 08 Jul 2015 09:10:07 EDTnews355565398New measurement of the mass of a strange atomic nucleus achieves very high precisionAn international team of physicists working at the Institute of Nuclear Physics at Johannes Gutenberg University Mainz (JGU) in Germany has measured the mass of a 'strange' atomic nucleus with the aid of an innovative technique that is capable of significantly greater precision than that of previous methods. The researchers were able, for the first time worldwide, to observe the radioactive decay of artificially generated nuclei of super-heavy hydrogen at the Mainz MAMI particle accelerator using a combination of several magnetic spectrometers. They could then precisely determine the mass on the basis of accurate measurement of the decay product. The results have been published in the journal Physical Review Letters.http://phys.org/news/2015-06-mass-strange-atomic-nucleus-high.html
General Physics Tue, 16 Jun 2015 17:49:04 EDTnews353695734New electron accelerator at JGU reaches first milestoneAs the production of two superconducting accelerator modules for the future electron accelerator MESA ("Mainz Energy-Recovering Superconducting Accelerator") at Johannes Gutenberg University Mainz (JGU) gets on its way, the MESA project launches into its next phase. MESA is based on a unique concept for recovering a part of the energy that is required for accelerating the electron beam. "The operating costs of MESA can thus be reduced significantly", said Professor Kurt Aulenbacher, head of the project team. MESA is the central instrument for several key experiments at the Cluster of Excellence "Precision Physics, Fundamental Interactions and Structure of Matter" (PRISMA). These include precision measurements of the proton radius and the search for so-called dark photons, i.e., particles that may explain the mystery of dark matter.http://phys.org/news/2015-06-electron-jgu-milestone.html

The light trapping process discovered last year involved twisting the polarization direction now appears to be related to a wide range of other seemingly unrelated phenomena. Also, physicist Robert Erlich claimed that neutrinos are likely tachyons, which would make them able to travel faster than light. He also believes the proof lies in finding the faster-than-light particles by weighing them. In space news, a team of Russian and American researchers found what they are calling the Milky Way's new neighbor—an isolated dwarf galaxy that lies almost 7 million light years away from us; they have named it KKs3. Also a pair of researchers proposed using ballistic capture as a cheaper path to Mars—it involves putting a space craft into the orbital path of the Red planet and waiting for the planet to catch up, rather than shooting directly at it.http://phys.org/news/2014-12-week-halting-photons-peer-problem.html

Galaxies are rarely found in isolation, but rather in sparse groups – sort of galactic urban sprawl. But there are occasional dense concentrations, often found in the center of giant clusters, but also, intriguingly, as more isolated compact groups (and yes, called Compact Galaxy Groups or CGs). The galaxies in these Compact Groups show dramatic differences in the way they evolve and change with time compared with galaxies in more isolated surroundings. Why is this? Collisions between galaxies in these dense groups are common, leading to rapid star formation, but there seems to be more to the puzzle.http://phys.org/news/2014-12-compact-galaxy-groups-reveal-encounters.html

Meanwhile, a team of physicists attempted to explain why some composite subatomic structures created at the Large Hadron Collider fell apart in unexpected ways during collisions, by reconsidering the math behind the underlying physics. Also, another team of researchers found a way to use real data rather than theory to measure the cosmos—they used data from astronomical surveys to measure a standard distance, suggesting that some current methods for measuring distance in the universe may be more complicated than they need to be.http://phys.org/news/2014-12-week-world-tabletop-mystery-earth.html
